Naphthalene is insoluble in water, somewhat soluble in methanol/ethanol, soluble in organic solvents and very soluble in ether, chloroform, or carbon disulfide.You could therefore use alcohol or methylated spirits.

If you're trying to neutralize the smell in clothes, airing them out works. If you're in a rush, you can place the clothes in a dryer (on low setting if the material is temperature sensitive), the heat helps to volatilize the odor faster. Remove the clothes and hang them in an open space while it's still warm.

If you're trying to neutralize the smell in a wood storage bin charcoal will soak up the napthalene vapor. It may take some time before most of it seeps out of the wood. The warmer it is the odor dissipates.
